Hinge



1938. P. WIMMENAUER 1 2 9 HINGE Filed Sept. ll, 1937 Inventar Patented Nov. l, 1938 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to a hinge, the general object of the invention being 130 provide the leaves of the hinge with parts having semispherical Sockets therein, and a spherical memher fitting in the Sockets Ior pivotally connecting the parts together so that the movable member can easi1y move on the other member and. Without noise.

This invention also consists in certain other features of construction and in the combination and arrangement of the severa1 parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, reference Will be had to the accompanying drawing Wherein 1ike characters denote 1ike or corresponding parts throughout the .several views, and in which:

Figure 1 is an elevation of parts of a door and its frame am}. showing two of the impro-ved hinges connecting the door with the frame, the upper hinge having parts in section.

Figure 2 is a top p1an view cf the improved hinge.

As shown in these views the hinge inclucles the two 1eaves l and 2 which are of the usual or any suitable construction and each leaf has a lateral extending part 3 extending from one side edge which is connected with a substantially frustro-conical member 4. The two members 4 of the hinge have the 1arge ends arranged adjacent each other and each 0f these ends has a semi-spherical recess 5 therein, the two recesses forming a substantially spherical space in which is located a spherical member er ball 6. The ba1l is large enough to slightly space the two members 4 apart and as will be seen the ba1l forms a pivotal connection between the two leaves of the hinge and that the mmber, such as the door A to which the leaves 2 are connectecl can readily swing with but litt1e friction and no noise on the frame B to which the leaves I are connected. A threaded sleeve 1 is located in a threaded hole in the upper mernber 4 and this member is adjusted to take up wear of theparts, the member being adjusted in any suitable manner though the drawing ShOWS it as being formed with a non-circular bore 8 for receiving any suitable form 0f tool so that it can be turned. This bore also acts as a passage for the lubricants used to lubricate the parts. As shown in Figure 1, the hinges are so arranged that the upper leaf on the door A has its socket part 4 located above the socket part of the adjacent 1eaf of the frame, and the lower 1eaf on the door has its socket part arranged below the adjacent socket part of the adjacent leaf on the frame. This arrangement prevents an upward movement of the door relative to the frame from separating the socket parts which would cause the 'door to fall from the frame.

It 1's thought from the foregoing description that the advantages and novel features of the invention will be reaclily apparent.

It 1's to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall Within the scope of the appended claim.

Having described the claim'ed as new is:

A hinge of the dass described comprising a pair 01 1eaves a laterally extend'ing portion formed on a part of one side edge of each leaf, a substantially frusto-cdnical member formed on the outer free edge of each laterally extending part, the frusto-conical part of one leaf being oppositely arranged with respect to that on the invention, what is vother leaf to plane the enlarged ends of said frusto-conical parts adjacent each other, each enlarged end. of the frusto-conical part having a semi-spherical recess therein, a spherical memher located in the space formed by the two recesses, one of said frusto-conical parts having a threaded bore passing from the recess through its small end and a. threaded sleeve in said bore having a concave recess in its inner end for engaging a portion of the spherical member, said sleeve forming means for taking up wear be-tween the parts.
